"Where dose the term ""horsepower"" come from?" Horsepower (hp) is the name of several non-metric units of power. The term horsepower was coined by the engineer James Watt (1736 to 1819) in 1782 while working in the performance of steam engines. This occurred while using a mine pony to lift coal out of a coal mine.

Horsepower Calculator Horsepower is a unit of measurement of power developed by engineer James Watt in the late 18th century. Although its original purpose was to compare the output of steam engines with the power of horses (hence its name), it has since been adopted as a unit of measurement for all sorts of engines used to power things such as vehicles, lawn mowers, boats, chainsaw, and airplanes.

- When we study with our families, we accomplish two things. First, we instill the teachings of God's word in our family life. Second, we remind our families that study of God's word is important and necessary. Spiritual leaders pray with their families. Families are difficult to nurture and protect in our society. So much is out there waiting to destroy the home, and sometimes, all our attempts at establishing security seem fruitless. That is why prayer is so vital. James said, The effective prayer of a righteous man can accomplish much (5:16).

Watts, Amps and Volts and How To Understand Electricity 1 Watt can be written 1W. We can calculate the power released in a bulb by multiplying the voltage in Volts across the bulb by the current in Amps flowing through the bulb (W = V x I). For example a current of 2 Amps flowing through a bulb with 12 Volts across it generates 24 watts of power. In the UK, domestic power is supplied at 240 Volts. A 100 Watt bulb will therefore draw a current of 100/240 Amps (about 0.4A).

horsepower (hp) The horsepower (hp) is a unit in the foot-pound-second ( fps ) or English system, sometimes used to express the rate at which mechanical energy is expended. It was originally defined as 550 foot-pounds per second (ft-lb/s). A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW). To convert from horsepower to watts, multiply by 746. To convert from watts to horsepower, multiply by 0.00134. To convert from horsepower to kilowatts, multiply by 0.746.

- Motor power is rated in horsepower and watts. Horsepower is used to measure the energy produced by an electric motor while doing work. To calculate the horsepower of a motor when current and efficiency, and voltage are known, apply this formula: HP = V x I x Eff 746 HP = horsepower V = voltage I = curent (amps) Eff.alculating Full-load Torque: Full-load torque is the torque to produce the rated power at full speed of the motor. The amount of torque a motor produces at rated power and full speed can be found by using a horsepower-to-torque conversion chart.
